UNHTED HARRY L. ALLEN, OF CLEVELAND, OHIO.

MACHINE FOR SHAPING AND TEMPERING METAL.

Application filed July 1,

To all whomvit may COILGGML.

Be it known that I, HARRY L. ALLEN, a citizen of the United States residing at Cleveland, in the county of duyahoga and State of Ohio, have invented a certain new and useful Improvement in Machines for Shaping and Tempering Metal, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

This invention relates to machines for shaping and tempering metal, and more particularly to machines which are designed for the cambering and tempering of spring plates.

The general purpose and object of this invention is to provide a machine of this character (consisting of a multiplicity of forms each adapted to shape a heated plate and reciprocable into and out of a quenching bath) which will secure not only the efficient shaping and'tempering of the plates clamped between the form members, but which will be capable of a maximum output of such tem- A further object of the invention is so to control the movements of the forms as to enable the plates to be conveniently applied to and removed from such forms and accomplish the quenching operation in the most effective manner. A further object of the invention is to provide a machine of this character with operating parts which are particularly adapted for the eflicient loading, unloading, and tempering operations, and which may be located within the. quenching bath without detriment to the continuous performance of their functions by the scale and other sediment deposited in such bath and upon and within such mechanism.

Further and more limited objects of the invention will appear hereinafter and will be realized in and through the embodiment thereof shown in the drawings, wherein Fig. 1 represents a sectional elevation of a machine constructed in accordance with my aforesaid invention. the view being taken back of. and adjacent to the front plate of the quenching tank; Fig. 2 a similar view taken at right angles to Fig. 1, the view being taken back of and adjacent to one of the sides of such tank; Figs. 3 and 4 sectional views corresponding approximately to the lines 33 and 4-4. of Fig. 1. respectively; and looking in the direction of the arrows. Fig. 5 a sectional plan view corresponding 1920. Serial N0. 393,357.

to the line 5-5 of Fig. 1 and showing in detail one of the guides for the lower form member and the manner in which the said member cooperates with such guide, and Fig. 6 a sectional'elevation of one of the guides, its support, and the stop for the lower form members.

Describing the parts by reference characters 1 represents the front wall, 2 the rear wall, 3 the bottom and t the sides of a quenching tank. This tank is provided with a connection 6, about the mid-height of its front wall, for the supply of oil or similar quenching liquid, in its rear wall with a combined skimmer and overflow connection 7 near the top of such wall, and near the bottom of one of the side walls with a drain connection 8.

The tank has mounted therein guides for a plurality of cambering forms, arranged in series between the front and rear wall there, of and reciprocable into and out of the liquid contained therein; also means for operating the said forms to permit the loading and unloading thereof, to cause the shaping of the metal plates between the members thereof, and for immersing such form members and the plates shaped thereby into the liquid within such tank. In the drawings four such forms are shown, but it will be obvious that their number may be increased or diminished, as desired.

Supported on the bottom of the tank is a framework comprising a pair of channel members 9 extending nearly from side to side thereof and adjacent to the front and back walls respectively. The upper portions of the members 9 are connected by channel members 10 extending nearly from the front to the back of the tank and located adjacent to the sides e, respectively. A similar framework is provided between the top and bottom of the tank, and, as shown, consists of a pair of channel members 11 located above the members 9, respectively, and a pair of channel members 12 located above the members 10 respectively.

Extending from near the bottom of the tank to near the top of the same are V- shaped guides 13, four such guides being located adjacent to each of the'side walls 4: and secured to the channels 10 and 12 and to upper channels 1 L parallel with the sides 4. respectively, by bolts 15, 15 and 15. Above the channels 14 and. preferably above the tank are channels 16, parallel, with the channels 1 1 respectively. The ends of the channels 10, 12, 14:, and 16 are bolted to corner channels 17, as shown. at 18, 18 18", and 18. Extending across the tops of the guides on each side of the tank is a-stop plate 19. (See Fig. 6). Each stop plate is preferably flush. with the top of a channel member 1 1 and may be secured tosuch memher by means of the bolts For this purpose, each stop plate is provided with an eye bolt 20 for each bolt 15", the latter bolt eX- tending through the eye 21 of the cooperating bolt 20 and theplate 19 being secured on top of the guides by means of nuts 22 on such eye bolts.

The guides 13 are employed with the lower members of the cambering forms, there being four such members and three such mem bers being shown in Fig; 1. These lower members are indicated generally at 23, 23 and 23!, and comprise each a base 2 1 having a head 25 thereabove, the said head being stepped and being provided withvertically adjustable bolts 26, the ends of which are adapted to contact with a plate 27, thereby to shape the same in connection with the corresponding bolts of an upper form member. The ends of each base 2 1 are connected, as by gusset plates 28, with a channel member 29. To each of the channel members, 29 there are connected a pair "of castings each having a base 30 at one end thereof secured to said channel by bolts 31. Opposite the said base, each casting is provided with a shoe 32 which is adapted to bear against opposite faces of the guide 13, the casting being recessed or cored at 33, to accommodate the ends of the bolts. Between the base 30 of each casting and the channel, one or more shims 3 1 may be inserted from time to time to compensate for the wear of the shoes and guides and to maintain each lower form member in proper relation to such guides.

Cooperating with each of the lower cambering form members is an upper member, four such members being shown and indi cated generally at 35, 35 35 and 35. Each upper member is provided with a plurality of adjustable bolts 36 opposed to the bolts '26 and cooperating therewith to shape and clamp a plate 27. The supporting base 37 for each upper form member is connected at its opposite ends, as by angle irons 38, to channel members 39, each having its flanges projected outwardly and adapted to slide within guides 29 provided therefor in the channel members 29. Secured to each of the channel members 39 is a rack 40. (See Figs.

1 and 5).

Cooperating with the channel members 16 are plates 11 which form supports for studs 42 on which are mounted pulleys 4L3. Connected to the upper ends of the channels 29 are the studs 44 supporting pulleys 15. cable or chain a6 is anchored at one end. to each of the members 16 and passes'a'lternatelyunder a pulley 15 and over a pulley 43 the opposite end of each such chain or cable being connected to a bolt i7 which extends through a series of counterweights l8, said counterweights extending transversely of and lo* cated within the rear portion of the tank. By this construction, the counterweight will, if unhindered, operate .upon the opposite ends of all of the lower cambering heads thereby to elevate the latter. p

'F or the purpose of operating the upper members of the fori'ns, to shape the plates applied to the lower members and to depress both members of the forms in opposition to the counterweights 18, the following construction is provided: 49 denotes an electric motor which may be mounted in any con.

venient position above the tank. The shaft 50 of this motor is provided with a pinion 51 meshing with a gear 52 on ashaft 53 which is ournaled upon one of the members 16. Mounted on the shaft 53 is a sprocket 54. A chain extends around said sprocket and a sprocket 56 in the lower portion of the tank. "The sprocket 56 is mounted upon a shaft 57 having a worm58 thereon mesh-- ing with a worm gear 59 which is bolted to the face of'a crank disk 60. This crank disk and two others, 6O" and 60", aremounted in suitable bearings 61 near the bottom of the tank. The disks 60 and 60 are connected to the central disk 60 by means of crank pins 62, arranged 180 apart. pin supports a pair of connecting rods 63, the journals for said pins being shown at 63 and each connecting rod is connected at its upper end to a segmental gear 64. Two sets of such segmental gears are shown,.each set comprising four such gears journaled on a common rod or shaft 65. The segmental. gears of one series mesh each with a gear of the opposite series and the crank pins are connected alternately with a gear of one se ries andthe next succeeding gear in the other series, the crank pins being arranged 90 apart. Each segmental gear meshes with a pinion 66 on a shaft 67, therebeing eight such pinions, mounted four each on a shaft, and said shafts being journaled in the channel members 11. Each shaft is provided with a series of four gears 68, each rigid with a pinion 66 and each meshing with one of the racks 40.

The various gears are immersed in the oil or other liquid contained within the tank, and hence are exposed to the action of the scale and other sediment deposited from the forms and the plates thereabove. .To pre-- vent the clogging of said gears, each one comprises a pair of flanges 69 (shown on the segmental gears) with the gear teeth 70 hav ing their opposite ends formed with or otherwise supported bysaid flanges and providing open spaces 71 between such teeth Each crank through which the scale or other sediment may drop i'reely. (See Fig. 1). The racks are constructed in like manner as indicated at l0? (Fig. 1) This enables me to employ the gears (it, 66. '68 and the said racks with-- outliability to interruption of the operation oi the machine by the accumulation of scale or other sediment between theteeth. The worm andworin gear will be provided with a housing 72 which will protect them from such scale or sediment.

lVith the parts arranged as described, the operation will be as follows: The operator will stand upon a tioor or platform arranged in convenient relation to the upper portion of the machine. In the drawings, the upper.

head oi the cambering form which is nearest to the front, or loading and unloading portion of the machine. has been moved to its extreme elevated position, through the motor 49 and the intermediate gearing up to and including the racks 40. and is moving downwardly until its shaping members or bolt-s are contacting with the spring plate 27, the said spring plate having been applied to the lower form-member 23,, the upward movement of which by the counterweights 48 has been arrested by the stops 19. During the interval of time between the arresting ol the upward movement of the lower cambering member and the upward and downward excursion of the corresponding upper member, the operator will have had ample opportunity to remove a previously shaped and tempered plate and to replace the same with a heated plate. Further downward movement of the upper and lower members causes both members to shape the plate and to be carried downwardly into the quenching liquid. The downward movement oi? this first cambering tl'orm enables the operator to remove a cam bered and tempered plate from the next form and to apply a heated plate to its lower member before the descent of the upper member c1 such form. In the drawings, two of the lower members are intheir uppermost or loading and unloading positions, the upper member corresponding to the first lower member moving downwardly and engaging a plate applied to said lower member. The head corresponding to the next form is in its extreme elevated position. The next form in order is about midway between its extreme upper and its extreme lower position and is moving upwardly, while therear form is in its extreme lowered position. As each form in turn reaches the loading position, the operator will have ample time to remove the shaped and quenched plate therefrom and replace the latter with a heated plate. Ofcourse, it necessary, the motor 49 may be stopped to suspend the operation of the machine for any desired length of time.

After an upper member has engaged the plate carried by thelower member, the .two

members move downwardly, then upwardly until such time as the upper shoe castings for the lower member engage thestop plates 19, the interposed plate meanwhile being subjected to a pressure determined by the counterweight.

. The crank connections employed for mow ing the upper form members cause the said members to move slowly between their uppermost positions and their plate-clamping andreleasing positions: to move both members rapidly into the quenching liquid from such clamping and releasing positions ---which is desirable in the heat treatment of the plates; and to retain the plates within the bath ltor a sufficient time to quench the same, thus giving a slowmovement at the times most desirable and a rapid immersion of the plates in the quenching liquid after the latter have been inserted within their proper forms.
